The EF 70–300mm f/4–5.6 IS II USM's NANO USM technology delivers quick, near-silent autofocus whether you're capturing an athlete jumping for a ball or recording wildlife in their natural habitat. For still images, it provides high-speed autofocus to help ensure you get the shot you want. When recording videos, the near-silent operation keeps unwanted noise out of your videos. For additional artistic control, manual focus is also possible even when the lens is set for autofocus. This means that when recording a video, for example, you can slowly pull in or out of focus for a dramatic effect.
The EF 70–300mm f/4–5.6 IS II USM features a new integral Lens Information Display for fast access to a wide variety of lens information. This lets you see the information you need at a glance, and then get right back to taking photos. The focusing distance display mode provides the distance the lens is focusing and an estimate of the depth-of-field, while the focal length display mode shows the 35mm-equivalent focal length. In shake amount display mode, the Lens Information Display gives an estimate of how much the lens and the camera are moving. To aid viewing in different lighting conditions, both black text on a light background or light text on a black background are selectable.
With an all-new design, the EF 70–300mm f/4–5.6 IS II USM features 12 groups with 17 total elements, including an optimally positioned UD lens. UD, or Ultra Low Dispersion, helps correct chromatic aberrations (colored halos around objects) while reducing color blurring and keeping overall detail high. This helps the EF 70–300mm f/4–5.6 IS II USM produce sharp, high-contrast, richly colorful images throughout its zoom range.
For consistently sharp results, the EF 70–300mm f/4–5.6 IS II USM features an improved Image Stabilizer system that provides significantly enhanced shake reduction for up to 4 stops of shutter speeds. This means more reliable handheld performance and clearer detail in low-light situations or at lower ISOs. Because of its enhanced stabilization, the EF 70–300mm f/4–5.6 IS II USM can also help minimize the need for a tripod.
Thanks to its 9-blade, circular aperture, the EF 70–300mm f/4–5.6 IS II USM is capable of gorgeous, evocative out-of-focus areas and soft backgrounds throughout its zoom range. By delivering an incredible level of control over background blur, it helps you create intimacy and intensity in your photos and videos for impactful results.
The EF 70–300mm f/4–5.6 IS II USM offers complete manual control, even when AF is engaged, with a simple twist of the lens's focus ring. Additionally, full-time manual focus means it's easy to achieve and maintain focus manually, which can be especially handy when shooting video or composing still images on a DSLR's screen.
